Improvement in flexible pipe-coupling



QUARTIIS RICE, CF NEVADA, CALIFORNIA, ASSIGNOR TC RANDOLPH CRAIG ANDJOSEIHICRAIG.

Letters Patent o. 97,699, dated December 7, 1869.

Th Schedule referred. to in these Letters Patent and making palt of thesame.

Be it known that I, QUARTUS RICE, of the city and county of Nevada, andState of California, have invented a new and useful Improvement on aFlexible Water-Pipe Coupling; and I do hereby declare that the followingis a full and clear description of the construction and operation of thesame, reference being had to the annexed drawings, said drawings makinga part of this'specification, in which- Iligure l is a side orlongitudinal elevation.

Figure 2 is a transverse section.

ySimilar letters of reference indicate corresponding parts in the twofigures.

A A is the supply-pipe, and -is fixed stationary.

B B is the discharge-pipe, to which the nozzle is attached.

In order to direct the stream in different directions, B B is by theconstruction of the flexible couplings D D D, which is capable of beingturned a full circle horizontally, and about forty-five degrees of acircle vertically.

It is found by experience that flexible water-pipe coupling, of theabove description and similar construction, when in u'se under a heavypressure caused by friction of the movable joint D D D, are immovablewith such force as is convenient to apply to said purpose.

1n order to diminish the friction of suitably-constructed flexiblewater-pipe couplings, I have constructed the anti-friction wheels E E E,the inverted circular plane L L L, the strap H H, the screw-bolt g g,the follower O, and the box m, the above-described devices beingconstructed to operate in combination.

It will be seen that by turning the screw-bolt g-g, the follower O, fig.2, will be pressed against a spring placed in the box in, and thereby adesirable portion ofthe pressure will be changed from the joint D D D tothe anti-friction wheels E E E and the inverted plane L L L, and, as thewheels roll instead of slipping on the plane, will allow the apparatusto operate freely, as described.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a flexible water-pipe coupling of any suitableconstruction, the anti-friction wheels E E E, in combination with theinverted circular plane L L L, substantially as and for the pur posesset forth.

2. The strap H H, the screw-bolt g g, follower O, and spring-box m, ortheir equivalents, for the purposes set forth.
